2014-05-21iwlwifi: mvm: pass force_assoc_off all the way down to avoid hacksLuciano Coelho4-16/+18
In some cases, we need to force the association to be off in the MAC_CONTEXT_CMD command we send to the firmware. Instead of having to hack the vif->bss_conf.assoc value, pass it all the way down the call chain. Additionally, for the iwl_mvm_mac_ctxt_add() case, we *always* set forced_assoc_off to true, so we can remove the hack in the d3 code that was forcing it to off by hacking the bss_conf.assoc value.

2014-05-21iwlwifi: mvm: don't filter out the first beaconAvri Altman3-52/+27
Enabling beacon filtering should be done only after a beacon has been received. Doing that too early will cause disconnections. This has already been fixed, but the fix didn't take care about the case where the beacon is received after the association, it waited only for association which is not enough.

2014-05-19ath9k_hw: Abort transmission for sleeping stationRajkumar Manoharan4-3/+31
The data transmission to the power save station should be aborted immediately, whenever the station informs sleep state. Right now the frames queued into into hardware are being transmitted until the hardware detects the power save station based excessive retries of the data frames due to unacknowlegdement. Then remaining frames are returned with filetered status and might be retried later by driver or mac80211. Per WFA certification testing, AP should not send out more than two frames after processing nullfunc with PM bit set from associated station. To speed up tx filtering, the pending frames in hardware queues for given station will be aborted immediately via tx filter registers. This transmit filters can be ignored if the descriptor is having invalid destination index or clear destination mask set. Signed-off-by: Rajkumar Manoharan <[email protected]> Signed-off-by: John W.

2014-05-16mwifiex: restore current SDIO write port in failure casesAvinash Patil1-1/+5
During SDIO MP aggregation, we at first acquire current write port to write data onto and then proceed with using this port for SDIO write. If error occurs later in mwifiex_write_data_sync because device is suspended or SDIO write failure, we do not restore current write port and write bitmap. This results into leaking one port and hole in SDIO write port bitmap. Restore current write port and reset bitmap accordingly in failure cases to avoid this.
